You can get a WiFi Dongle that connects to your PC or a LAN adapter that plugs into one of the USB ports. Also, the USB dongle for the DS is the same as the one for the Wii, so if you want the freedom of wireless or want to kill two birds with one stone I'd suggest the WiFi Dongle, or just getting a WiFi router, but there's also the LAN option.

You can have a wired connection to your network. Though WiFi is a lot cleaner...I'd spend the money on the nintendo WiFi router. It's not too expensive and it saves you from having to keep your Wii next to your computer/modem.

Expect you can't be too far either. -_-; The Wifi adapter only has a 20 foot range, I think.
